我正在尝试在客户端获取选定的网格行KeyField值;

我曾经尝试过以下各种结果:

方法#1

<ClientSideEvents RowClick="function(s, e) {var key= grid.GetSelectedKeysOnPage()[0];}" />
//This gives previous selected rows value everytime

方法#2

<ClientSideEvents RowClick="function(s, e) { grid.GetRowValues(grid.GetFocusedRowIndex(), 'MyKeyFieldName', OnGetRowValues); }" />
//This gives previous selected row and also gives an error: "A primary key field specified via the KeyFieldName property is not found in the underlying data source. Make sure.. blabla" But the MyKeyFieldName is true and i dont want to make a callback, i dont want to use this method!

方法#3

<ClientSideEvents RowClick="function(s, …

我将GridView从工具箱拖放到Aspx页面.设计代码如下所示

<asp:GridView ID="gridview1" runat="server"   style="text-align:center;width: 1327px;" 
    CellPadding="4" ForeColor="#333333" GridLines="None" AllowPaging="True" 
    EnableSortingAndPagingCallbacks="True" PageSize="50" AutoGenerateEditButton="True">
    <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
    <EditRowStyle BackColor="#999999" />
    <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
    <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
    <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" 
        Height="12px" VerticalAlign="Bottom" Width="12px" Wrap="False" />
    <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
    <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
    <SortedAscendingCellStyle BackColor="#E9E7E2" />
    <SortedAscendingHeaderStyle BackColor="#506C8C" />
    <SortedDescendingCellStyle BackColor="#FFFDF8" />
    <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
</asp:GridView>

我在数据库中有一个名称地址列.使用以下VB.NET代码将表绑定到此网格视图

 Dim ds as Data.DataSet
 Dim da As New OleDbDataAdapter("select col1,col2,col3,col4,col5,col6,col7,col8,col9,col10,Address from table, con)
        da.Fill(ds)
        gridviewrealestate.DataSource = ds
        gridviewrealestate.DataBind() …

我已经通过将groupindex赋予aspxgridview中的特定列来对网格进行分组.

例如,如果我通过人名进行分组,并且当单击箭头以查看内容时,该特定人员制作的订单详细信息将包含在详细内容中.

当我点击标题字段进行排序时,它正在对groupContent内的数据进行排序,但它不用于排序groupsum的数据

除了人名之外,我将所有总计作为小组摘要的一部分显示.

例如,如果您在以下链接中看到:

https://demos.devexpress.com/ASPxGridViewDemos/Summary/GroupSortBySummary.aspx

如果按公司名称排序,则会对内容进行排序,但显示国家/地区和总和的摘要无法在外部排序.

请建议我选择解决这个问题.

谢谢.

我在ASPxGridView中有这样的复选框:

<dxwgv:ASPxGridView ID="Grid_Loading_Plan_Detail" runat="server" >          
...
<dxwgv:GridViewDataColumn Caption="#" VisibleIndex="1">
<DataItemTemplate>
<dxe:ASPxCheckBox ID="loadingStatus" runat="server" Checked='<%# GetChecked(Eval("loadingStatus").ToString()) %>'></dxe:ASPxCheckBox>
</DataItemTemplate>
</dxwgv:GridViewDataColumn>
...
</dxwgv:ASPxGridView>

它在加载复选框时很好地绑定,这里的函数:

Public Function GetChecked(value As String) As Boolean
    Select Case value
        Case "1"
            Return True
        Case "0"
            Return False
        Case Else
            Return False
    End Select
End Function

问题是,当检查checked状态时,它总是返回加载的值.如果状态是checked第一次加载然后我执行uncheckedCheckBox,它仍然会返回checked.这里我如何获取值并将其保存到数据库:

Protected Sub btSimpan_Click(sender As Object, e As EventArgs) Handles btSimpan.Click
    Try
        sqlstring = ""
        For i As Integer = 0 To Grid_Loading_Plan_Detail.VisibleRowCount - 1 …

我在如何通过点击网格视图内的按钮显示模态面板时遇到了很多困难.

上下文:我有一个数据行,其字符串字段可以包含简单文本或base 64编码图像,因此我使用自定义模板来定义何时显示原始内容或按钮"查看图像".此图像将在模式面板上打开,该面板应在按钮单击时上升.

这是我作为控件(ascx)创建的Panel:

<asp:Panel ID="pnlModalOverlay" runat="server" Visible="true" CssClass="Overlay">
    <asp:Panel ID="pnlModalMainContent" runat="server" Visible="true" CssClass="ModalWindow">
        <div class="WindowTitle">
            <asp:Label ID="lbTitle" runat="server" />
        </div>
        <div class="WindowBody">
            <asp:Panel ID="pnlContent" runat="server" Visible="true">
                <asp:Image ID="imgContent" runat="server" CssClass="ImageView" />
            </asp:Panel>
            <div class="Button">
                <asp:Button ID="btnOk" runat="server" class="btn btn-default " Text="Close" OnClientClick="loadingPanel.Show();" />
            </div>
        </div>
    </asp:Panel>
</asp:Panel>

这是我想要使用它的页面和ASPxGridView:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
    <ContentTemplate>
        <div style="margin-top: 12px;">
            <asp:Button type="button" ID="btnShowImage" AutoPostBack="true" class="btn btn-default navbar-right" Text="Show Image"
                runat="server" Style="margin-left: 5px;" OnClientClick="loadingGridPanel.Show();" />
        </div> 

        <!-- Some data filter controls  -->

        <MyWorkspace:AlertModal …

我有ASPxGridview这样的:

有没有什么办法计算的总GroupSummary对TotalSummary 不进行分组.

GroupSummary's  SummeryType="AVERAGE"

例如:

MUS_K_ISIM   GroupSummary[RISK_EUR]
2M LOJ?ST?K  123.456 
ABA LOJ?STIK 234.567 

然后我想要TotalSummary的RISK_EUR列是123.456 + 234.567 = 358023.

注意:我只想用普通的Gridview进行计算.不做分组.

另一个例子:

Customer_No Customer_Name Price
123         aaa           50
123         aaa           100
123         aaa           60
124         bbb           60
125         ccc           20
125         ccc           40

我想要那个网格:

What is avarage of 123 number customer = 50 + 100 + 60 = 210/3= 70
What is avarage of 124 number customer = 60/1=60 …

我使用DevexpressGridView来显示所有内容 TOPIC (id,title,content)

<dx:ASPxGridView ID="gv" runat="server"
OnSelectionChanged="gv_SelectionChanged" >

我有grid_SelectionChanged事件:

protected void gv_SelectionChanged(object sender, EventArgs e)
    {

        int id= selected row...???; //how can I get the value of selected row
        string sql = "select * from TOPIC where idTOPIC="+id;
        DataTable topic = l.EXECUTEQUERYSQL(sql);
        TextBox1.Text = topic.Rows[0][1].ToString();
    }

...

似乎gv.SelectedRowDevGridview中不存在方法.

按照建议,我尝试过使用FocusedRowIndex方法,但我真的不知道正确的语法来获取所选行的值.

救命!!!

我需要使用DevExpress ASPxGridView.我有一个数据源对象,它返回两个重要的列,ObjectType和ObjectID.ObjectType可以是患者或医生.ObjectID是一个i​​nt值,给出患者或医师的ID.希望这是有道理的.ObjectID由Patient表或Physician表选择,它们是indendent表,因此我无法以任何方式加入它们.

表结构如下所示:

对象表:ObjectType varchar("Physician"或"Patient"),ObjectID int

Dogs Table ID int,Name varchar

Cats表ID int,名称varchar

我已经能够通过组合框来编写适当的objectType,并使用两个控件cbPatient和cbPhysician来编写ObjectID,这些控件由数据源填充.

我无法弄清楚当我编辑ASPxGridView时,如何在cbPatient或cbPhysician中显示对象值.例如,如果ObjectType是Cats并且ObjectID是1,那么我想在cbCats中显示与ID为1对应的名称.

这就是代码的外观.现在,无论出于何种原因,在某些情况下,所选值在某些时候变为空白.我不确定要运行此代码的事件.

protected void grid_HtmlRowCreated(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewTableRowEventArgs e)
{
    if (e.RowType != DevExpress.Web.ASPxGridView.GridViewRowType.EditForm) return;
    if (grid.IsNewRowEditing || grid.IsEditing)
    {
        int val = (int)grid.GetRowValues(grid.EditingRowVisibleIndex, "ObjectID" );

        ASPxComboBox cbPatient = ((ASPxComboBox)grid.FindEditRowCellTemplateControl(grid.Columns["PatientID"] as GridViewDataComboBoxColumn, "cbPatient"));
        if (val != 0)
        {
            string objectID = grid.GetRowValues(grid.EditingRowVisibleIndex, "ObjectID").ToString();

            if (cbPatient.Items.Count > 0)
            {
                cbPatient.Items[1].Selected = true;
            }
            else
            {
                cbPatient.DataSource = dsPatName;
                cbPatient.DataBindItems();
                if (cbPatient.Items.Count > 0)
                    cbPatient.Items[1].Selected = true;
            }

        } …

嗨,我已经使用gridview创建一个表.有没有办法实现编辑和删除.我以前用PHP做过.我想要使​​用的方法是在表中再创建两列,每行包含编辑和删除按钮.然后,当单击按钮时,它会通过URL传递"id"并能够编辑或删除.不确定如何在asp.net webforms中执行此操作.下面是我的表格代码.谢谢.

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
    <asp:BoundField HeaderText="Surgery" DataField="surgery" />
    <asp:BoundField HeaderText="PatientID" DataField="patientID" />
    <asp:BoundField HeaderText="Location" DataField="location" />

</Columns>          

SqlCommand cmd = new SqlCommand("select surgery, patientID, location from details", conn);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);

conn.Close();

GridView1.DataSource = dt;
GridView1.DataBind();

这很简单.我想要做的就是在asp:Griview中插入一个隐藏的列,我将能够通过javascript访问它.有什么指针吗？
